- 論文の詳細を見る
The ultimate aim of this research is to improve the robustness of the air gap controller for solid immersion lens (SIL)-based near-field (NF) servo systems against the external shocks. To detect gap error and read-out signals for the SIL and the disk, the air gap control performance must be increased to avoid collisions due to external shocks. We propose an anti-shock air gap control system using a quadrant Q filter and a dead-zone non-linear controller. Experimental results demonstrate that a quadrant Q filter and a dead-zone non-linear controller maintained the optical head with SIL optics distance for a 4.48 G@10 ms shock. Thus the control performance in the presence of external shocks was improved.
